no, its not.
thats the solution offered by spyre on their forums, and its wrong. the first link in my sig is about me getting banned from the ATI forums for pointing out their "solution" doesnt work - let me provide a screenshot as proof (the act that got me banned)
Note that the native res is stated as 1080P while the resolution is lower (and apply is greyed out, so i have hit apply) - not there.
To make it work you have to go below 1280x1024 (an issue fixed for XP around cat 8.5, but ignored for 7 - it was in a change log), and even that doesnt work for some people.
The question is - why is this needed? why cant the setting be applied at ANY resolution, since it has no effect unless you lower it?
